The 2S raise was inadvisable since it promises 3 card support and there is nothing about the hand pattern or the nature of the 2 card spade tolerance that is noteworthy or suggestive that the partnership truly belongs in spades. A negative/card showing Double or Pass would be fine.
I prefer the Double because, if your and LHO both Pass and partner reopens with a Double, 3C does not do justice to the hand (unless you play Good/Bad 2NT here) and either 2NT or 4C seem speculative.
Regardless, 4S clearly was an overbid. A game try is reasonable and, to that end, a natural 2NT seems about right.

I largely agree with Caitlynne's comments here. However, I think that Pass, not Double, is right with the West hand. If East reopens with a Double, the standard bid is/should be 2NT showing this hand with clubs. That's because a negative Dbl risks 3D from opener and then West would be stuck. Switch West's clubs and diamonds, however, and a negative Dbl is best because now West can correct East's bid of 3C with 3D.
Of course, I have to wonder why East did not open 1NT. Perhaps, however, that is avoided with a small doubleton?
